Asdefined in the 3rd Generation Partnership Project (3GPP), the differencebetween each unit may be differentiated as an entire (or whole) targetnetwork unit (APN or PDN unit), units being differentiated by QoS withinthe entire (or whole) target network unit (Bearer units), anddestination IP address units.

APN: This is an abbreviation for an Access Point Name, which is the nameof an access point being managed by the network, and this name isprovided to the UE. More specifically, this is a character stringindicating or identifying a PDN. A corresponding P-GW needs to be passedthrough in order to access a requested service or network (PDN). And,the APN is a name (character string) that is defined in advance in orderto find (or locate) the P-GW. For example, the APN may be defined asinternet.mnc012.mcc345.gprs.

The following description of this specification may be applied to anext-generation (also known as 5^(th) generation or 5G) mobilecommunication network.

Next-Generation Mobile Communication Network

Thanks to the success of long term evolution (LTE)/LTE-advanced (LTE-A)for 4G mobile communication, interest in the next generation, i.e.,5-generation (so called 5G) mobile communication has been increased andresearches have been continuously conducted.

The 5G mobile telecommunications defined by the InternationalTelecommunication Union (ITU) refers to providing a data transmissionrate of up to 20 Gbps and a feel transmission rate of at least 100 Mbpsor more at any location. The official name is ‘IMT-2020’ and its goal isto be commercialized worldwide in 2020.

ITU proposes three usage scenarios, for example, enhanced Mobile BroadBand (eMBB) and massive machine type communication (mMTC) and ultrareliable and low latency communications (URLLC).

URLLC relates to usage scenarios that require high reliability and lowlatency. For example, services such as autonomous navigation, factoryautomation, augmented reality require high reliability and low latency(e.g., a delay time of 1 ms or less). Currently, the delay time of 4G(LTE) is statistically 21 to 43 ms (best 10%) and 33 to 75 ms (median).This is insufficient to support a service requiring a delay time of 1 msor less. Next, an eMBB usage scenario relates to a usage scenariorequiring a mobile ultra-wideband.

That is, the 5G mobile communication system aims at higher capacity thanthe current 4G LTE, may increase the density of mobile broadband users,and may support device to device (D2D), high stability and machine typecommunication (MTC). 5G research and development also aims at a lowerlatency time and lower battery consumption than a 4G mobilecommunication system to better implement the Internet of things. A newradio access technology (New RAT or NR) may be proposed for such 5Gmobile communication.

FIG. 1 Illustrates an Example of Wireless Communication System.

As seen with reference to FIG. 1, the wireless communication systemincludes at least one base station (BS). The BS is classified into a gNB20 a and an eNB 20 b. The gNB 20 a is for 5G mobile communication suchas NR. And, the eNB 20 b is for 4G mobile communication such as LTE orLTE-A.

Each BS (e.g., gNB 20 a and eNB 20 b) provides a communication serviceto specific geographical areas (generally, referred to as cells) 20-1,20-2, and 20-3. The cell can be further divided into a plurality ofareas (sectors).

The UE 10 generally belongs to one cell and the cell to which the UEbelong is referred to as a serving cell. A BS that provides thecommunication service to the serving cell is referred to as a servingBS. Since the wireless communication system is a cellular system,another cell that neighbors to the serving cell is present. Another cellwhich neighbors to the serving cell is referred to a neighbor cell. A BSthat provides the communication service to the neighbor cell is referredto as a neighbor BS. The serving cell and the neighbor cell arerelatively decided based on the UE.

Hereinafter, a downlink means communication from the BS 20 to the UE 10and an uplink means communication from the UE 10 to the BS 200. In thedownlink, a transmitter may be a part of the BS 20 and a receiver may bea part of the UE 10. In the uplink, the transmitter may be a part of theUE 10 and the receiver may be a part of the BS 20.

Meanwhile, the wireless communication system may be generally dividedinto a frequency division duplex (FDD) type and a time division duplex(TDD) type. According to the FDD type, uplink transmission and downlinktransmission are achieved while occupying different frequency bands.According to the TDD type, the uplink transmission and the downlinktransmission are achieved at different time while occupying the samefrequency band. A channel response of the TDD type is substantiallyreciprocal. This means that a downlink channel response and an uplinkchannel response are approximately the same as each other in a givenfrequency area. Accordingly, in the TDD based wireless communicationsystem, the downlink channel response may be acquired from the uplinkchannel response. In the TDD type, since an entire frequency band istime-divided in the uplink transmission and the downlink transmission,the downlink transmission by the base station and the uplinktransmission by the terminal may not be performed simultaneously. In theTDD system in which the uplink transmission and the downlinktransmission are divided by the unit of a subframe, the uplinktransmission and the downlink transmission are performed in differentsubframes.

FIGS. 2 a to 2 c are Exemplary Diagrams Illustrating ExemplaryArchitectures for Services of the Next Generation Mobile Communication.

Referring to FIG. 2 a, the UE is connected to LTE/LTE-A based cells andNR based cells in a dual connectivity (DC) manner.

The NR-based cell is connected to a core network for existing 4G mobilecommunication, that is, an evolved packet core (EPC).

Referring to FIG. 2 b, unlike FIG. 2 a, the LTE/LTE-A based cell isconnected to a core network for the 5G mobile communication, that is, anext generation (NG) core network.

The service scheme based on the architecture as illustrated in FIGS. 2aand 2B is called non-standalone (NSA).

Referring to FIG. 2 c, the UE is connected only to NR-based cells. Theservice method based on such an architecture is called standalone (SA).

On the other hand, in the NR, it may be considered that the receptionfrom the base station uses a downlink subframe, and the transmission tothe base station uses an uplink subframe. This method may be applied topaired spectra and unpaired spectra. A pair of spectra means that thetwo carrier spectra are included for downlink and uplink operations. Forexample, in a pair of spectra, one carrier may include a downlink bandand an uplink band that are paired with each other.

FIG. 3 Illustrates an Example of a Structure of NR Radio Frame.

In the NR, the uplink and downlink transmission are based on radioframes. The radio frame has a length of 10 ms and may be defined as two5 ms half-frames (HFs). The half-frame may be defined as five 1 mssubframes (SFs). The subframe is divided into one or more slots, and thenumber of slots in the subframe depends on the subcarrier spacing (SCS).Each slot includes 12 or 14 OFDM (A) symbols according to the cyclicprefix (CP). When the normal CP is used, each slot includes 14 symbols.When the extended CP is used, each slot includes 12 symbols. Here, thesymbol may include an OFDM symbol (or CP-OFDM symbol) and an SC-FDMAsymbol (or DFT-s-OFDM symbol).

FIG. 4 Shows an Example of Subframe Type in NR.

A transmission time interval (TTI) shown in FIG. 4 may be called asubframe or slot for NR (or new RAT). The subframe (or slot) in FIG. 4may be used in a TDD system of NR (or new RAT) to minimize datatransmission delay. As shown in FIG. 4, a subframe (or slot) includes 14symbols as does the current subframe. A front symbol of the subframe (orslot) may be used for a downlink control channel, and a rear symbol ofthe subframe (or slot) may be used for a uplink control channel. Otherchannels may be used for downlink data transmission or uplink datatransmission. According to such structure of a subframe (or slot),downlink transmission and uplink transmission may be performedsequentially in one subframe (or slot). Therefore, a downlink data maybe received in the subframe (or slot), and a uplink acknowledge response(ACK/NACK) may be transmitted in the subframe (or slot). A subframe (orslot) in this structure may be called a self-constrained subframe. Ifthis structure of a subframe (or slot) is used, it may reduce timerequired to retransmit data regarding which a reception error occurred,and thus, a final data transmission waiting time may be minimized. Insuch structure of the self-contained subframe (slot), a time gap may berequired for transition from a transmission mode to a reception mode orvice versa. To this end, when downlink is transitioned to uplink in thesubframe structure, some OFDM symbols may be set as a Guard Period (GP).

Support of Various Numerologies

The NR supports a plurality of numerologies (e.g. a plurality of valuesof subcarrier spacing (SCS)) in order to support various 5G services.For example, when the SCS is 15 kHz, a wide area in traditional cellularbands is supported. When the SCS is 30 kHz/60 kHz, a dense-urban,lower-latency, and wider carrier bandwidth is supported. When the SCS is60 kHz or greater, a bandwidth greater than 24.25 GHz is supported inorder to overcome phase noise.

In the next generation system, with development of wirelesscommunication technologies, a plurality of numerologies may be providedto a UE.

The numerologies may be defined by a length of cycle prefix (CP) and asubcarrier spacing. One cell may provide a plurality of numerology to aUE. When an index of a numerology is represented by μ, a subcarrierspacing and a corresponding CP length may be expressed as shown in thefollowing table.

Table 1 exemplarily shows that when the normal CP is used, the number ofsymbols per slot, the number of slots per frame, and the number of slotsper subframe vary according to the SCS.

TABLE 1 SCS (15*2{circumflex over ( )}u) N^(slot) _(symb) N^(frame, u)_(slot) N^(subframe, u) _(slot) 15 KHz (u = 0) 14 10 1 30 KHz (u = 1) 1420 2 60 KHz (u = 2) 14 40 4 120 KHz (u = 3)  14 80 8 240 KHz (u = 4)  14160 16 *N^(slot) _(symb): The number of symbols in slot *N^(frame, u)_(slot): The number of slots in frame *N^(subframe, u) _(slot): Thenumber of slots in subframe

Table 2 exemplarily shows that when the extended CP is used, the numberof symbols per slot, the number of slots per frame, and the number ofslots per subframe vary according to the SCS.

TABLE 2 SCS (15*2{circumflex over ( )}u) N^(slot) _(symb) N^(frame, u)_(slot) N^(subframe, u) _(slot) 60 KHz (u = 2) 12 40 4

In the NR system, OFDM (A) numerology (for example, SCS, CP length, andthe like) may be set differently between a plurality of cells mergedinto one terminal. Accordingly, a (absolute time) section of a timeresource (for example, SF, slot, or TTI) (commonly referred to as a timeunit (TU) for convenience) composed of the same number of symbols may beset differently between the merged cells.

Meanwhile, in the next-generation mobile communication, each symbol maybe used for downlink or uplink, as shown in an example of the followingtable. In the following table, uplink is indicated by U, and downlink isindicated by D. In the following table, X indicates a symbol that can beflexibly used for uplink or downlink.

For example, thetwo types (FR1 and FR2) of frequency bands are illustrated in Table 1.For the convenience of description, among the frequency bands used inthe NR system, FR1 may refer to a “sub-6-GHz range”, FR2 may refer to an“above-6-GHz range” and may be referred to as a millimeter wave(mmWave).

TABLE 4 Frequency Range Corresponding Designation Frequency RangeSubcarrier Spacing FR1  450 MHz-6000 MHz 15, 30, 60 kHz FR2 24250MHz-52600 MHz 60, 120, 240 kHz

As described above, the frequency ranges for the NR system may bechanged. For example, FR1 may include a range from 410 MHz to 7125 MHzas illustrated in Table 5. That is, FR1 may include a frequency band of6 GHz or greater (or 5850, 5900, 5925 MHz, or the like). For example,the frequency band of 6 GHz or greater (or 5850, 5900, 5925 MHz or thelike) included in FR1 may include an unlicensed band. The unlicensedband may be used for various uses, for example, for vehicularcommunication (e.g., autonomous driving).

Carrier Aggregation

A carrier aggregation system is now described.

A carrier aggregation system aggregates a plurality of componentcarriers (CCs). A meaning of an existing cell is changed according tothe above carrier aggregation. According to the carrier aggregation, acell may signify a combination of a downlink component carrier and anuplink component carrier or an independent downlink component carrier.

Further, the cell in the carrier aggregation may be classified into aprimary cell, a secondary cell, and a serving cell. The primary cellsignifies a cell operated in a primary frequency. The primary cellsignifies a cell which UE performs an initial connection establishmentprocedure or a connection reestablishment procedure or a cell indicatedas a primary cell in a handover procedure. The secondary cell signifiesa cell operating in a secondary frequency. Once the RRC connection isestablished, the secondary cell is used to provide an additional radioresource.

Carrier aggregation may be classified into a continuous carrieraggregation in which aggregated carriers are continuous and anon-contiguous carrier aggregation in which aggregated carriers areseparated from each other. In the following, carrier aggregation simplyshould be understood to include both the case where the componentcarrier (CC) is continuous and the case where it is discontinuous. Thenumber of CCs aggregated between the downlink and the uplink may be setdifferently. A case in which the number of downlink CCs and the numberof uplink CCs are the same may be referred to as symmetric aggregation,and a case in which the number of downlink CCs are different may bereferred to as asymmetric aggregation.

On the other hand, carrier aggregation can also be classified intointer-band CA and intra-band CA . The inter-band CA is a method ofaggregating and using each CC existing in different operating bands, andthe intra-band CA is a method of aggregating and using each CC in thesame operating band. In addition, the CA technology is morespecifically, intra-band contiguous CA, intra-band non-contiguous CA andinter-band discontinuity. Non-Contiguous) CA.

FIG. 5 a Illustrates a Concept View of an Example of Intra-BandContiguous CA. FIG. 5 b Illustrates a Concept View of an Example ofIntra-Band Non-Contiguous CA.

LTE-advanced adds various schemes including uplink MIMO and carrieraggregation in order to realize high-speed wireless transmission. The CAmay be split into the intra-band contiguous CA shown in FIG. 5a and theintra-band non-contiguous CA shown in FIG. 5 b.

FIG. 6 a Illustrates a Concept View of an Example of a Combination of aLower Frequency Band and a Higher Frequency Band for Inter-Band CA. FIG.6 b Illustrates a Concept View of an Example of a Combination of SimilarFrequency Bands for Inter-Band CA.

The inter-band carrier aggregation may be separated into inter-band CAbetween carriers of a low band and a high band having different RFcharacteristics of inter-band CA as shown in FIG. 6a and inter-band CAof similar frequencies that may use a common RF terminal per componentcarrier due to similar RF (radio frequency) characteristics as shown inFIG. 6 b.

In Table 9, N_(RB) may mean Transmission bandwidth configuration,expressed in units of resource blocks.

The following table is an example of CA bandwidth classes andcorresponding nominal guard band BW_(GB).

NOTE 2: a₁= 0.16/1.4 for BW_(Channel(1)) = 1.4 MHz whereas a₁ = 0.05 for all otherchannel bandwidths. NOTE 3: Applicable for later releases.

In Table 10, BW_(GB) may mean nominal guard band. The nominal guard bandmay mean a virtual guard band to facilitate transmitter (or receiver)filtering above/below edge CC (Component Carrier)s. N_(RB,agg) may meanthe number of aggregated RBs within a fully allocated Aggregated Channelbandwidth.

FIG. 7 Illustrates an Example of Situation in Which an Uplink SignalTransmitted Via an Uplink Operating Band Affects Reception of a DownlinkSignal on Via Downlink Operating Band.

In FIG. 7, Intermodulation Distortion (IMD) may mean amplitudemodulation of signals containing two or more different frequencies,caused by nonlinearities or time variance in a system. Theintermodulation between frequency components will form additionalcomponents at frequencies that are not just at harmonic frequencies(integer multiples) of either, like harmonic distortion, but also at thesum and difference frequencies of the original frequencies and at sumsand differences of multiples of those frequencies.

Referring to FIG. 7, an example in which a CA is configured with aterminal is shown. For example, the terminal may perform communicationby using the CA based on three downlink operating bands (DL Band X, Y,Z) and two uplink operating bands (DL Band X, Y).

As shown in FIG. 7, in a situation in which three downlink operatingbands are configured by the CA and two uplink operating bands areconfigured by the CA, the terminal may transmit an uplink signal throughtwo uplink operating bands. In this case, a harmonics component and anintermodulation distortion (IMD) component occurring based on thefrequency band of the uplink signal may fall into its own downlink band.That is, in the example of FIG. 7, when the terminal transmits theuplink signal, the harmonics component and the intermodulationdistortion (IMD) component may occur, which may affect the downlink bandof the terminal itself.

The terminal should be configured to satisfy a reference sensitivitypower level (REFSENS) which is the minimum average power for eachantenna port of the terminal when receiving the downlink signal.

When the harmonics component and/or IMD component occur as shown in theexample of FIG. 7, there is a possibility that the REF SENS for thedownlink signal may not be satisfied due to the uplink signaltransmitted by the terminal itself

For example, the REF SENS may be set such that the downlink signalthroughput of the terminal is 95% or more of the maximum throughput ofthe reference measurement channel. When the harmonics component and/orIMD component occur, there is a possibility that the downlink signalthroughput is reduced to 95% or less of the maximum throughput.

Therefore, when the harmonics component and/or IMD component occur,whether the harmonics component and the IMD component of the terminaloccur may be determined, and the maximum sensitivity degradation (MSD)value is defined for the corresponding frequency band, so relaxation forREFSENS in the reception band related to its own transmission signal maybe allowed. Here, the MSD may mean the maximum allowed reduction of theREF SENS. When the MSD is defined for a specific operating band of theterminal, which configured with the CA, the REFSENS of the correspondingoperating band may be relaxed by the amount of the defined MSD.

Various combinations of downlink operating bands and uplink operatingbands may be used for the CA. For example, for LTE-A inter-band CA,combinations of n (n=3, 4, 5) downlink operating bands and two uplinkoperating bands may be used.

Hereinafter, the LTE-A inter-band CA using combinations of n (n=3, 4, 5)downlink operating bands and two uplink operating bands may also bereferred to as n bands (n=3, 4, 5) DL/2 bands UL, or n DL/2 ULinter-band CA.

Conventionally, the impact of harmonics and/or IMD on some combinationsin the CA case based on n bands DL/2 bands UL combinations has not beenanalyzed and the MSD values have not been discussed. For example, theimpact of the harmonics and/or IMD for a combination of a CA_2A-13A-66A-66B downlink band and a CA_13A-66A uplink band, and acombination of a CA_2A-48A-66A downlink band and a CA_48A-66A uplinkband of Table 11, which will be described later, among 3 bands DL/2 bandUL combinations is not analyzed, and the MSD values have not beendiscussed.

In the CA case based on n bands DL/2 bands UL combinations, the terminalmay perform dual uplink transmission through two uplink operating bands.In this case, the MSD value for analyzing the impact of the harmonicsand/or IMD occurring in the downlink operating band other than theuplink operating band used for the dual uplink transmission among the ndownlink operating bands and relaxing the REF SENS specification needsto be proposed.

Hereinafter, the impact of the harmonics and/or IMD in the CA case basedon the n bands DL/2 bands UL combinations is analyzed. In addition, theMSD value for relaxing the RESENS specification based on the analyzedresults is proposed.

For example, self-interference (for example, interference due to theharmonics and/or IMB) occurring in the terminal, which configuredwthLTE-A inter-band CA (3 bands DL/2 bands UL), may be analyzed. Inaddition, the MSD value may be set based on the analyzedself-interference, and a reference sensitivity specification, which isrelaxed due to the MSD, may be defined.

In other words, in the present disclosure, for the terminal, whichconfigured with the 3 DL/2 Uplink LTE-A inter-band CA to performcommunication, the impact of the self-interference (harmonics and/or 1MB) occurring in another downlink band other than the uplinktransmission bands may be analyzed. In addition, in the presentdisclosure, the maximum sensitivity degradation (MSD) value may beproposed in consideration of a radio frequency (RF) structure in acombination of bands in which the impact of self-interference isanalyzed. The proposed MSD makes it possible to make exceptions to thereference sensitivity of the band (for example, to relax the REFSENSbased on the MSD value). The reference sensitivity to which theexceptions are applied during the terminal test may be applied to theterminal, and the terminal may pass the terminal test based on theapplied reference sensitivity

As described above, for the combination of the UL operating band and theDL operating band having the self-interference problem, the MSD needs tobe determined.

Among the 3 bands DL/2 bands UL combinations, for the 3 bands DL/2 bandsUL combinations (that is, 3 bands DL/2 bands UL combination CA operatingband combinations), the MSD for one downlink band (one of the threedownlink bands) affected by the harmonic and/or IMD occurring during thedual uplink transmission based on two UL operating bands may be providedbelow.

For 4 bands DL/2 band UL CA band combinations and 5 bands DL/2 bands ULCA band combinations, no additional analysis is needed for harmonicsand/or IMD in DL bands (4th and 5th bands) corresponding to the sameE-UTRA operating band as the UL band. This is because all self-defenseproblems are addressed by a combination of the 2 bands DL/2 bands UL andthe 3 bands DL/2 bands UL CA. For example, the 5 bands DL/2 bands UL CAcombination includes a 3 bands DL/2 bands UL CA combination and a 2bands DL/2 bands UL CA combination. Therefore, for the 5 bands DL/2bands UL CA combination, the analysis results of the 3 bands DL/2 bandsUL CA combination and the 2 bands DL/2 bands UL CA combination can bereused, and as a result, no additional analysis is needed for the/2bands UL CA combination.

Table 11 below shows an example of the 3 bands DL/2 bands UL CA bandcombination associated with the self-interference problem.

In Table 11, 3rd band without uplink means a downlink operating bandthat does not overlap two uplink operating bands among three downlinkoperating bands used for the CA.

For example, in the CA_2A-13A-66A-66B downlink band and CA_13A-66Auplink band combination, the 3rd band without uplink means downlinkoperating band 2. As another example, in the CA_2A-48A-66A-66B downlinkband and CA_13A-66A uplink band combination, the 3rd band without uplinkmeans the downlink operating band 2.

Here, the CA_2A-13A-66A-66B downlink band may mean that downlinkoperating bands 2, 13, and 66 are used, and the CA 13A-66A uplink bandmay mean that uplink operating bands 13 and 66 are used.

The CA_2A-48A-66A downlink band may mean that downlink operating bands2, 13, 48, and 66 are used, and the CA_48A-66A uplink band may mean thatuplink operating bands 48 and 66 are used.

Alphabets (A, B, C, D, and the like) after the number refer to abandwidth class described in the example of Table 10. For example, theCA_2A-13A-66A-66B downlink band means that CC with bandwidth class Aand/or B in downlink operating band 66, CC with bandwidth class A and CCwith bandwidth class B are used in the downlink operating band 2, andthe CC with the bandwidth class A is used in the downlink operating band2, and the CC with the bandwidth class A is used in the downingoperating band 13.

Referring to Table 11, the self-interference problem of the combinationof the CA_2A-13A-66A-66B downlink band and the CA_13A-66A uplink band,and the combination of the CA_2A-48A-66A downlink band and theCA_48A-66A uplink band is not analyzed. That is, the MSD values for thecombination of the CA_2A-13A-66A-66B downlink band and the CA_13A-66Auplink band and the combination of the CA_2A-48A-66A downlink band andthe CA_48A-66A uplink band are not defined.

Hereinafter, the 4th IMD for the downlink operating band 2 will beanalyzed for the combination of the CA_2A-13A-66A-66B downlink band andthe CA_13A-66A uplink band. The 2nd IMD and 5th IMD for the downlinkoperating band 2 will be analyzed for the combination of CA_2A-48A-66Adownlink band and the CA_48A-66A uplink band. Based on the analysisresults, the MSD values for the combination of the CA_2A-13A-66A-66Bdownlink band and the CA_13A-66A uplink band and the combination of theCA_2A-48A-66A downlink band and the CA_48A-66A uplink band will bedetermined.

FIG. 8 Illustrates an Example of IMD 4 for CA with Downlink Bands 2, 13,66 and Uplink Bands 13, 66.

FIG. 8 shows an example of the IMD 4 affecting the downlink band 2 inthe combination of the CA_2A-13A-66A-66B downlink band and CA_13A-66Auplink band.

Referring to FIG. 8, a 4^(th) order IMD (IMD 4) component of an uplinksignal transmitted in the uplink band 13 and an uplink signaltransmitted in the uplink band 66 may fall into a frequency range of thedownlink band 2.

The worst case where the impact of the IMD 4 within the frequency rangeof the downlink band 2 is greatest is the case where a center frequencyof the uplink band 13 is 782 MHz, a center frequency of the uplinkoperating band 66 is 1762 MHz, and a center frequency of the downlinkoperating band 2 is 1960 MHz. In this case, since 1762*2−782*2=1960, thefrequency of the IMD4 component of the uplink bands 13 and 66 coincideswith the center frequency of the downlink band 2.

FIG. 9 Illustrates an Example of IMD 2 for CA with Downlink Bands 2, 48,66 and Uplink Bands 48, 66.

FIG. 9 shows an example of the IMD 2 affecting the downlink band 2 inthe combination of the CA_2A-48A-66A downlink band and the CA_48A-66Auplink band. Although only an example of the IMD 4 is shown in FIG. 9,the IMD 5 affecting the downlink band 2 may also be generated in thecombination of the CA_2A-48A-66A downlink band and the CA_48A-66A uplinkband.

Referring to FIG. 9, a 2^(nd) order IMD (IMD 2) component of an uplinksignal transmitted in the uplink band 66 and an uplink signaltransmitted in the uplink band 48 may fall into a frequency range of thedownlink band 2.

The worst case where the impact of the IMD 2 within the frequency rangeof the downlink band 2 is greatest is the case where a center frequencyof the uplink band 66 is 1735 MHz, a center frequency of the uplinkoperating band 66 is 3695 MHz, and a center frequency of the downlinkoperating band 2 is 1960 MHz. In this case, since 3695−1735=1960, thefrequency of the IMD4 component of the uplink bands 48 and 66 coincideswith the center frequency of the downlink band 2.

Table 12 shows an example of RF component parameters of the UE used toanalyze the IMD and determine the MSD value.

Based on simulation based on the isolationparameters in Table 13, the IMD problem and MSD for the downlinkoperating band 2 are analyzed in the combination of theCA_2A-13A-66A-66B downlink band and the CA_13A-66A uplink band, and thecombination of the CA_2A-48A-66A downlink band and the CA_48A-66A uplinkband.

Based on simulation based on the isolation parameters in Table 13 and UEreference architecture and the RF component parameters in Table 12, theIMD problem and MSD for the downlink operating band 2 are analyzed inthe combination of the CA_2A-13A-66A-66B downlink band and theCA_13A-66A uplink band, and the combination of the CA_2A-48A-66Adownlink band and the CA_48A-66A uplink band.

Hereinafter, FIGS. 10 and 11 are examples of an RF structure of aterminal based on components to which parameters of Table 12 and Table13 are applied. Based on the RF structure according to the example ofFIG. 10, the IMD and the MSD of the combination of the CA_2A-13A-66A-66Bdownlink band and the CA_13A-66A uplink band may be analyzed. Based onthe RF structure according to the example of FIG. 11, the IMD and theMSD of the combination of the CA_2A-48A-66A-66B downlink band and theCA_48A-66A uplink band may be analyzed. For reference, for the B48filter of FIG. 11, the same parameters as the duplexers of Table 12 andTable 13 are applied.

For reference, in FIGS. 10 and 11, DPX may mean a duplexer, PA may meana power amplifier, and DIP may mean a diplexer. In addition, RFIC mayrefer to a radio-frequency integrated circuit.

Thetransceiver(s) 106 of the first wireless device 100 may include the RFstructure according to the examples of FIGS. 10 and 11.

FIG. 10 Illustrates an Example of Terminal's RF Structure Used forAnalyzing IMD and MSD for CA with Downlink Bands 2, 13, 66 and UplinkBands 13, 66.

When the uplink CA_13A_66A (bands 13 and 66) is paired with the downlinkCA_2A-13A-66A-66B (bands 2, 13, and 66), the 4th order IMD componentoccurring by the uplink band 13 and the uplink band 66 may affect an Rxfrequency band 2 (that is, downlink band 2) of the terminal itself. Thatis, 4th the order IMD may fall into downlink band 2.

Based on the example of the RF structure shown in FIG. 10, the 4th orderIMD component affecting the downlink band 2 is analyzed, and the MSDvalue determined based on the analyzed IMD is 6.2 dB of Table 14 below.

FIG. 11 Illustrates an Example of Terminal's RF Structure Used forAnalyzing IMD and MSD for CA with Downlink Bands 2, 48, 66 and UplinkBands 48, 66.

When the uplink CA_48A_66A (bands 48 and 66) is paired with the downlinkCA_2A-48A-66A (bands 2, 48, and 66), the 2nd order IMD and the 5th orderIMD component occurring by the uplink band 48 and the uplink band 66 mayaffect the Rx frequency band 2 (that is, downlink band 2) of theterminal itself. That is, the 2nd order IMD and the 5th order IMD mayfall into the downlink band 2.

Based on the example of the RF structure shown in FIG. 11, the 2nd orderIMD and 5th order IMD components affecting the downlink band 2 isanalyzed, and the MSD value determined based on the analyzed IMD is 28.3dB and 0 dB of Table 14 below.

As described above, based on the simulation based on Tables 12, 13, andFIGS. 10 and 11, the IMD problem and MSD for the downlink operating band2 are analyzed in the combination of the CA_2A-13A-66A-66B downlink bandand the CA_13A-66A uplink band, and the combination of the CA_2A-48A-66Adownlink band and the CA_48A-66A uplink band.

For example, for the worst case where the impact of IMD on downlinkoperating band 2 is the greatest in the two CA band combinations,simulations based on Tables 12, 13, 10, and 11 are performed. The IMDand MSD analyses are performed according to the simulations performed,and the MSD values determined according to the analysis results areshown in Table 14.

Table 14 shows the MSD values applicable to the downlink operation band2 in the CA_2A-13A-66A-66B downlink band and CA_13A-66A uplink band, andthe combination of the CA_2A-48A-66A downlink band and the CA_48A-66Auplink band.

In Table 14, Fc means a center frequency. For example, UL Fc may meanthe center frequency of the uplink operating band or the centerfrequency of the CC in the uplink operating band. CLRB may meanTransmission bandwidth which represents the length of a contiguousresource block allocation expressed in units of resource blocks.

When the terminal receives the downlink signal through the downlinkoperation band 2 in the combination of the CA_2A-13A-66A-66B downlinkband and the CA_3A-66A uplink band, and the combination of theCA_2A-48A-66A downlink band and the CA_48A-66A uplink band, the MSDvalues in Table 14 can be applied to the reference sensitivity for thedownlink operating band 2.

For example, the MSD values in Table 14 may be applied to minimumrequirements that the terminal, which is configured with the CA based onthe combination of the CA_2A-13A-66A-66B downlink band and theCA_13A-66A uplink band, should satisfy. That is, the MSD may be appliedto the reference sensitivity of the downlink operating band 2. In otherwords, the reference sensitivity of the downlink operating band 2 may berelaxed by 6.2 dB.

As another example, the MSD values in Table 14 may be applied to theminimum requirements that the terminal, which is configured with the CAbased on the combination of the CA_2A-48A-66A downlink band and theCA_48A-66A uplink band, should satisfy. That is, the MSD may be appliedto the reference sensitivity of the downlink operating band 2. In otherwords, the reference sensitivity of the downlink operating band 2 may berelaxed by 28.3 dB.

Potential IMD problems can occur in the combination of theCA_2A-13A-66A-66B downlink and the CA_13A-66A uplink band, and thecombination of the CA_2A-48A-66A downlink band and the CA_48A-66A uplinkband, and therefore, it is suggested to apply the MSD values in Table 14to the reference sensitivity of the downlink operating band 2.

The reception performance of the terminal can be tested by applying theMSD values in Table 14 to the reference sensitivity of the downlinkoperating band 2. In other words, the MSD values in Table 14 may beapplied to the reference sensitivity of the downlink operating band 2used when the reception performance of the terminal is tested. Thetransceiver (or receiver) of the terminal that passed the test satisfiesthe minimum requirements based on the reference sensitivity to which theMSD values in Table 14 apply.

The terminal (for example, first device 100 of FIG. 14) may include atleast one transceiver (for example, transceiver(s) 106 of FIG. 14), atleast one processor (for example, processor(s) 102 of FIG. 14). Theterminal may also include at least one memory (for example, memory(s)104 of FIG. 14. The transceiver may be configured to use a plurality ofE-UTRA operating bands. For example, the CA may be configured such thatthe transceiver uses E-UTRA operating bands 2, 13, and 66 as a downlinkband (for example, CA_2A-13A-66A-66B downlink band) and uses E-UTRAoperating bands 13 and 66 as an uplink band (for example, CA_13A-66Auplink band). As another example, the transceiver is configured with theCA to use the E-UTRA operating bands 2, 13, and 66 as the downlink band(for example, CA_2A-48A-66A-66B downlink band) and use the E-UTRAoperating bands 13 and 66 as the uplink band (for example, CA_48A-66Auplink band). At least one processor may be operably connectable to thetransceiver. A processor may control the transceiver. At least onememory is operably connectable to at least one processor and at leastone transceiver. The at least one memory may store instructions that maybe executed by at least one processor. The at least one processor mayexecute instructions stored in at least one memory. The operationsperformed by the processor may be performed by executing instructionsstored in the memory. At least one processor may control at least onetransceiver to transmit an uplink signal through at least two (forexample, bands 13 and 66 or bands 48 and 66) of the plurality of E-UTRAoperating bands. At least one processor may control at least onetransceiver to receive a downlink signal through at least three (forexample, bands 2, 13, and 66 or bands 2, 48, and 66) of the plurality ofE-UTRA operating bands. The combination of the at least two bands andthe at least three bands may be a combination set for the CA. That is,the terminal may perform communication using the CA based on thecombination of the at least two downlink operating bands and the atleast three downlink operating bands. As in the example of Table 14, apreset MSD value may be applied to the reference sensitivity for theE-UTRA operating band 2.

Hereinafter, FIG. 12 illustrates an example of an operation performed bythe terminal.

FIG. 12 is a Flow Chart Showing an Example of a Procedure of a TerminalAccording to the Present Disclosure.

Referring to FIG. 12, steps S1210 to S1230 are shown. Operationsdescribed below may be performed by the terminal (for example, the firstdevice 100 of FIG. 14).

For reference, step S1210 may not always be performed when the terminalperforms communication. For example, step S1210 may be performed onlywhen the reception performance of the terminal is tested.

In the terminal performing the operation of FIG. 12, the CA based on thecombination of three downlink bands and the two uplink bands may beconfigured. For example, the combination of three downlink bands and twouplink bands may be the combination of the CA_2A-13A-66A-66B downlinkband and the CA_13A-66A uplink band or the combination of theCA_2A-48A-66A downlink band and the CA_48A-66A uplink band.

In step S1210, the terminal may preset the MSD value. For example, theterminal may preset the MSD values in Table 14. For example, for thecombination of the CA_2A-13A-66A-66B downlink band and the CA_13A-66Auplink band, an MSD of 6.2 dB may be applied to the referencesensitivity of the downlink band 2. As another example, for thecombination of the CA_2A-48A-66A-66B downlink band and the CA_13A-66Auplink band, an MSD of 28.3 dB or 0 dB may be applied to the referencesensitivity of the downlink band 2.

In step S1220, the terminal may transmit the uplink signal.

When the combination of the CA_2A-13A-66A-66B downlink band and theCA_13A-66A uplink band is configured in the terminal, the terminal maytransmit the uplink signal through at least one of the uplink operatingbands 13 and/or 66.

When the combination of the CA_2A-48A-66A downlink band and theCA_48A-66A uplink band is configured in the terminal, the terminal maytransmit the uplink signal through at least one of the uplink operatingbands 48 and/or 66.

In step S1230, the terminal may receive the downlink signal.

The terminal may receive the downlink signal based on the referencesensitivity of the downlink band 2, to which the MSD value is applied.

When the combination of the CA_2A-13A-66A-66B downlink band and theCA_13A-66A uplink band is configured in the terminal, the terminal mayreceive the downlink signal through at least one of the downlinkoperating bands 2, 13, and/or 66.

When the combination of the CA_2A-48A-66A downlink band and theCA_48A-66A uplink band is configured in the terminal, the terminal mayreceive the downlink signal through at least one of the downlinkoperating bands 2, 48, and/or 66.

For reference, the order in which steps S1220 and S1230 are performedmay be different from that shown in FIG. 12. For example, step S1230 maybe performed first and then step S1220 may be performed. Alternatively,step S1220 and step S1230 may be performed simultaneously.Alternatively, the time when step S1220 and step S1230 may be mayoverlap partially.

The output z of the precoder 1040may be obtained by multiplying the output y of the layer mapper 1030 bythe precoding matrix W of N*M. Where N is the number of antenna portsand M is the number of transport layers.

The received wireless signal may beconverted into a baseband signal through a signal recoverer. To thisend, the signal recoverer may include a frequency downlink converter, ananalog-to-digital converter (ADC), a CP canceller, and a fast fouriertransform (FFT) module.
